Is bitcoin really that profitable
- - talking about the mining cost of bitcoin -
the first thing to consider is the cost if you want to make money. If the profit is greater than the cost, it is worth doing. We all know how much bitcoin costs, so let's calculate the cost
1. Mining machine cost: the "number" of bitcoin is a problem-solving process, which can't be calculated by human brain alone. Therefore, mining people need to buy mining machines and keep calculating. The more mining machines, the stronger the computing power
2. Electricity charges: mining machines are big consumers of high power. How much electricity does it consume? Let's put it this way. At present, the electricity consumption of bitcoin and Ethereum mining has surpassed Jordan, Iceland, Libya and other small countries, ranking 71st among all countries and regions in the world. You want to cry when electricity is expensive
3. The rent of the place where the mining machine is placed: because the mining machine consumes a lot of electricity, the power supply load of ordinary residential buildings can not be guaranteed at all, so the mining must rent a commercial site separately, and the rent is much more expensive than that of ordinary residential buildings
4. Operation cost: in order to ensure the computing power, the high-power mining machine needs to work 24 hours, which requires someone to maintain it at any time. When the mining machine is in trouble, the cost of hiring someone is required; At the same time, the mining machine is very delicate. If it is too hot or too cold, the vegetables will be stopped. Therefore, the measures of cold air and cold water insulation are needed to help the mining machine run. This is another expense
5. Mining machine update cost: because bitcoin is becoming more and more difficult to dig, the machine that was able to dig a month ago may not be able to dig anything today, and the market will also launch mining machines with greater computing power. The original mining machine is not worth money immediately. If you want to maintain computing power, you need to buy mining machines again
the above bitcoin mining costs all have a marginal effect, that is, the larger the volume is, the lower the corresponding cost will be. Therefore, some super large mines have been built
bitcoin g in the mine will enter the mine pool and be distributed by all participants. Large mines will be built in places where labor and electricity are cheap, such as Venezuela, the legendary miner's paradise, or Iceland, where the climate is favorable and electricity is cheap
as for the cost, everyone will be different. Let's take a look at an average: in 2017, according to the data of elite fixtures, a research institution, Venezuela is the cheapest of 115 mining countries, which is 513 US dollars, while South Korea is the most expensive, which is 26170 us dollars
China's mining cost is US $3172, which is relatively low among 115 countries. However, the cost is an average value. Large mines with low electricity prices must be much lower. If you are a lone ranger, the cost will rise sharply
in a word, if you really want to make money by mining, first of all, unless you are rich enough to build a mine with thousands of machines, you'd better join a mine to dig together. Although you have to share the money, it's still appropriate in the long run because it can greatly rece costs and improve computing power
secondly, whether you dig by yourself or join the mine, you must choose the place with low electricity cost, and the city with abundant hydropower resources is preferred, because hydropower is the cheapest source of power generation in China at present.
I have been working in a mine and trading coins for many years.
There are risks
on the one hand, the Internet real name system can become the "iron broom" to sweep away bad information, on the other hand, it will make all Internet platforms become "fat meat" in the eyes of hackers, increasing the risk of personal information leakage of Internet users
according to the analysis report on the situation of personal information leakage from websites in 2016 released by 360 patch day vulnerability platform in March 2017, 58.5% of the website vulnerabilities in 2016 will lead to the leakage of real name information, 62.4% of the website vulnerabilities will disclose behavior information, and the number of possible leaks can reach 4.23 billion and 4.01 billion
according to insiders, hackers often get users' registration information on Internet platforms and sell it to lawless elements by "scanning numbers and colliding libraries", but many platforms still lack effective defense measures against this "colliding library attack"
extended data:
holds up the "umbrella" of personal information for real name netizens
the major Internet platforms graally improve their own defense systems from both technical and regulatory aspects to prevent hacker attacks from leading to user information leakage. It is understood that a security team has been set up on an Internet shopping platform to discover high-level persistent threats on the internal network based on the security risk detection and identification of network security attacks, mine and detect phishing websites targeting buyers and businesses, and deal with them in a timely manner
the relevant departments of the state have successively issued various laws and regulations to ensure the information security of Internet users
"China's" decision on strengthening the protection of network information "," tort liability law "and its judicial interpretation and a series of legal provisions have repeatedly stressed the issue of personal information security. It can be seen that China's network information security and personal data security have been raised to the highest level of the country, and strict legal proceres and clear legal authorization are required for the use and collection of personal information. "
Zhu Wei, deputy director of the communication law research center of China University of political science and law, believes that under such a background, the comprehensive establishment of the real name system can actually strengthen the personal information security protection of users
2. The purpose is that the global currency, as far as the world's central banks are concerned, has the power to arbitrarily increase the money supply, leading to currency devaluation and stealing the global people's labor income
3. Therefore, this carrier can't be changed arbitrarily. Some people will regard it as a currency carrier. Just like the gold and silver of that year, these currencies of that year can be used as currency carriers because of the scarcity of non-ferrous metals
4. What's the use of money carrier? It's for circulation and preservation. If the central bank has restrictions, it is not allowed to increase the money supply at will, so that people's labor income will depreciate. In fact, electronic money is the most convenient. How heavy is gold and silver? Even the transaction of bitcoin is very inconvenient and cannot be used as a currency transaction
5. So, as long as someone believes in it, as long as someone is willing to hype it, there will be a price. If you think about it, the price of tulip, which was scarce in those years, could fly as long as it was hyped
6. When everyone thinks that this thing is meaningless and not hyped, then there is no price for this thing.
